你打开MATLAB后，FIle->New->GUI弹出guide对话框，OK。然后就可以根据你的需要添加相应的控件，然后在自动生成的GUI界面代码中添加相应的代码。比如在yourGUIname_OpeningFcn(),pushbutton1_Callback()等函数中添加代码就可以了。第一次设计时，弄个简单的，如一个加法计数器界面，找点相关的知识，参考一下，入门后就简单了。
要看你是从事网站界面设计还是软件界面设计。网站界面设计，必须了解一些简单的html、div、css样式表等基本语言；软件界面设计，就要了解其产品所用的是什么工具做的，软件和硬件的兼容性问题（性能问题）。
对于设计软件，常用的有photoshop、网页3剑客、uidesigner等工具就可以了。
